High Intensity (85% MHR)
High Intensity (95% MHR)
At rest
Which would be the main contributing energy system in this physical activity?
ATP-PC System
Lactic Acid System
Aerobic System
The anaerobic glycolysis system
operates without oxygen
provides energy for about 10 seconds to 90 seconds
is used for high intensity exercise
all of the above
none of the above
Which of the following fuels can be used to produce energy?
Carbohydrates
Proteins
Fats
all of the above
none of the above
The energy system used for a particular activity will depend on the:
intensity of the activity
duration of the activity
both of the above
none of the above
What fuels will the aerobic energy system use?
Phosphocreatine
Glucose and Glycogen
Fat, Glycogen and Protein
Glycogen and Fat
Which energy system produces energy the slowest?
ATP-Pcr
Lactic Acid
Aerobic
This energy is stored in our cells and is called
Oxidative triphosphate (OTP)
adenosine criphosphate (ATC).
Adenosine triphosphate (ATP).
Anaerobic means
without oxygen (ATP – PC and Lactic acid systems)
"with oxygen", and refers to the use of oxygen in the body's energy generating process (Aerobic energy system).
Aerobic means

"with oxygen", and refers to the use of oxygen in the body's energy generating process (Aerobic energy system).
How long does the ATP-CP system last?
2mins+ Long term energy
0 seconds up to 2 minutes Short term high intensity
Immediate high intensity (0-10seconds)
What is the major energy system used in long distance running?
ATP-CP
Anaerobic
Aerobic
Which of these defines the word 'replenish'?
Return to a normal state of mind or strength after a period of exertion
Resume (an activity) after an interruption
Use up (resources or reserves) completely
Restore (a stock or supply) to a former level or condition
Why does the body require the three different energy systems?
It doesn't require three different systems
Different sports have different demands
Intensity and duration of different activities and the availability of oxygen
Physical exercise usually takes longer than a few minutes
